    I don't know about this thing. It's more of a novelty than something I would trust to be accurate.

    The idea was fun and a good tool; however, the app to run the device would never work accurately.

    Great device, works like it's supposed to. Great way to determine if you had to much to drink. Apps help you find a way home.

    I saw this on sale at Best Buy during Black Friday and thought it was a joke. I picked one up for fun and it makes for a great conversation piece. You shouldn't use this to measure your BAC before getting behind the wheel, but rather when hanging out with your friends and having a good time. Remember, drive sober or get pulled over!

    The battery door doesn't stay shut. Junky. Brought it back to the store and got the blue tooth one. Don't have to plug it into the phone. It's great!

    Always gave me a message "try again for accuracy" Talked to the manufacturer, all they told me to do was "take it outside and wave it in the air for 10 seconds"
